It is possible to improve the throughput of an entire system while reducing power consumption. A mobile communication system includes a mobile station device and a base station device. According to uplink channel quality information, the base station device generates an interference information table and transmits the interference information index table to the mobile station device.According to the interference information index table, the mobile station device judges the state of interference of an uplink frequency band, decides the frequency band of a measurement pilot channel as a pilot channel used for judging the reception quality, and makes a transmission resource request to the base station device. For example, the mobile station device decides the frequency band having the least interference in the uplink frequency band to be the frequency band of the measurement pilot channel.

La présente invention concerne l'amélioration du débit d'un système complet tout en réduisant la consommation énergétique. Un système de communication mobile comprend un dispositif de station mobile et un dispositif de station de base. Selon une information de qualité de canal de liaison montante, le dispositif de station de base génère une table d'information d'interférence et transmet la table d'index d'information d'interférence au dispositif de station mobile. Selon la table d'index d'information d'interférence, le dispositif de station mobile décide l'état d'interférence d'une bande de fréquence de liaison montante, juge la bande de fréquence d'un canal pilote de mesure comme un canal pilote utilisé pour décider de la qualité de réception, et fait une demande de ressource de transmission au dispositif de station de base. Par exemple, le dispositif de station mobile décide la bande de fréquence ayant la moindre interférence dans la bande de fréquence de liaison montante pour être la bande de fréquence du canal pilote de mesure.
